GeForce 6800 GT

2008

Why buy it

  • Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

  • Less VRAM, with 256 MB vs 1 GB for high-resolution textures and newer games.
  • 2008 hardware with 256 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 150.9% HIGHER MSRP
    $399 MSRPvs$159 MSRP
  • Lower G3D Mark per dollar, at 0.4 vs 0.9 G3D/$ ($399 MSRP vs $159 MSRP).
  • 24.9% longer card at 216mm vs 173mm.

GeForce 8600 GT

2008

Why buy it
